VectorCoordinate GeometryGeometric Construction
This example demonstrates vector addition using the parallelogram and triangle laws through visualization, helping to understand the geometric meaning of vector addition. Core mathematical concepts include vectors, geometric construction, and coordinate representation. It utilizes GeoGebra commands like Vector, Line, Intersect, and Segment, along with objects such as O, A, B, u, v, w, a, Q, C, D, etc. Suitable for middle school students and above to learn vector operations, also applicable for physics teaching on mechanics.

GeoGebra Commands & Parameters

  1. Vector(O, A) → u
  2. Vector(A, B) → v
  3. Vector(O, B) → w
  4. Vector(Q, C) → b
  5. Vector(Q, D) → c
  6. Line(D, b) → d
  7. Line(C, c) → e
  8. Intersect(d, e) → E
  9. Vector(Q, E) → f
  10. Segment(C, E) → g
  11. Segment(E, D) → h
